Victorian style Christmas carolers figurines family vintage Japan, 60s retro holiday decor

Set of vintage Christmas carolers in a 60s 'Victorian' style, so retro! They're made in Japan, ceramic or a sort of composition material. They range in height from 6 1/2" to 10" tall.

There's some weird discoloration or marking to their faces which I'm not sure about - maybe it's a sort of antiqued look? It doesn't look like they've been scribbled on or anything like that. No chips or cracks, they've been carefully stored away for about 50 years.
